i2c: Provide FFDC data in the driver
Define SRCs of I2C component and interface with the existing
skiboot 'errorlog' infrasturcute for commiting the logs. Add the
i2c specific OPAL error codes to differentiate various types of
errors during i2c operations.
To ease debugging, dump the i2c register contents, 'master' and
'request' structure bits in case any error occured during transfer
on the bus. Minor clean-ups as well.
